From 35dc81410518e6d39ba8b3f99348884778bedc5b Mon Sep 17 00:00:00 2001 From: Dirk Hohndel Date: Sat, 4 Jul 2015 09:12:54 -0700 Subject: Add simple test for the dive planner This sets up a standard dive scenario (30 minutes at 260ft/79m, EAN36 and Oxygen as deco gases, last stop at 20ft/6m) and calls the planner to set up a dive plan given certain standard gases. Instead of trying to verify the complete plans it checks that we switch to the deco gases at the right depth and the complete duration of the dive matches our expectation. The test intentionally fails right now for imperial as we have the wrong switch depth for Oxygen. See how useful tests are? On the downside, the test does NOT produce the same plan as Subsurface when I try to create a consistent setup for both - and I have not been able to figure out why. There must be some other parameters that I'm not setting, but I haven't identified them, yet. It's very small differences, for example in the metric case the stops at 21m, 9m, and 6m are each one minute shorter in the test than it what Subsurface calculates.
